Florida Dental Radiography Certification: Requirements and Training

The short answer

Florida Statutes allow a dentist to direct a dental assistant to expose dental X-rays, subject to the Board of Dentistry's rules.^[1] The Board's rule, 64B5-9.011, sets the training an assistant needs before doing so independently: at least three months of continuous on-the-job training under the direct supervision of a Florida-licensed dentist, followed by a Board-approved radiography course completed within 12 months of that training.^[2] The assistant then applies to the Department of Health for dental radiographer certification.^[3]

There is a second route. The Board states that someone who completed a Board-approved expanded duty program is not required to obtain the separate radiographer certification.^[4] Rule 64B5-16.002 likewise treats radiography formal training as satisfied through the Rule 64B5-9.011 certification process.^[5]

The trainee window: X-rays during on-the-job training

People are often surprised that an uncertified assistant can take radiographs at all. The rule makes it possible on purpose: the three months of on-the-job training are training in positioning and exposing radiographs, under the dentist's direct supervision.^[2] Direct supervision has a specific meaning in Florida — the dentist examines the patient, orders the procedure, remains on the premises while it is performed, and checks the result before the patient is dismissed.^[6]

That window is not open-ended. The course must follow within 12 months of completing the on-the-job training, and certification is not issued until the Board has the application, the $35 fee and Livescan fingerprint results.^[2][7][8] An assistant who completed the three months years ago and never took the course is not certified.

Why dentists should care about the paperwork

Responsibility runs to the licensee. Delegating professional responsibilities to a person the dentist knows, or has reason to know, is not qualified by training, experience or licensure is grounds for disciplinary action under §466.028(1)(z).^[9] The practical defense is simple: verify the certificate when you hire, keep a copy, and confirm it is displayed as required.

Verification takes a minute on the Department of Health's license verification search, which covers certificate holders.^[10] For an assistant certified through a Board-approved program, keep the program's certificate of completion on file.

Being allowed to take X-rays vs. taking good ones

Certification is the legal floor. The research is a reminder of why the training content matters. A literature review by dental radiologists at the University of Hong Kong pooled 26 studies and found average reject rates of 11.25 percent for bitewings and 16.38 percent for periapicals; positioning error and patient movement were two of the most common reasons.^[11] Every rejected image is a retake, and every retake is additional radiation for the patient.

Technique errors are common even under good conditions. A 2026 study of 962 bitewing examinations from 31 Swedish public dental practices found the quality requirements fully met in only 5 percent and acceptable in 43 percent; incorrect sensor placement appeared in 94 percent of examinations.^[12] A 2026 JADA study from the Université de Montréal found that rectangular collimation — which narrows the beam to the size of the sensor — reduces patient dose by 50 to 60 percent without a significant change in the overall retake rate, while warning that “special attention must be paid to cone positioning and clinical training.”^[13]

The current professional guidance comes from dentists, too. An expert panel convened under the American Dental Association published radiation safety recommendations in 2024, stressing that fundamental principles of radiation protection, consistent with federal, state and local requirements, are essential for limiting patient exposure.^[14] In January 2026 the ADA and the American Academy of Oral and Maxillofacial Radiology updated the selection criteria for dental imaging: a thorough history and clinical exam should precede radiographs, and every imaging modality should be used judiciously.^[15] The dentist decides which images a patient needs; the assistant's job is to capture them correctly the first time. The ADA/AAOMR selection recommendations are worth reading for anyone who exposes radiographs.

Good news: technique is teachable. In a 2026 Journal of Dental Education study from Marmara University's oral and maxillofacial radiology department, one or more technical errors were found in 81.6 percent of 960 images taken by dental students using the bisecting technique without a film holder, and sensor positioning was the most common error. The authors studied whether a practical demonstration reduced those errors — the kind of structured, hands-on instruction that separates a real course from a quick video.^[16] That is why Florida's rule requires hands-on positioning practice rather than theory alone.^[2]

In practice, most retakes trace back to a handful of habits: the sensor not placed far enough back to capture the apices or the distal of the canine, the beam not aligned with the holder ring (cone cuts), overlapping contacts from an incorrect horizontal angle, and the patient moving or not biting fully. Each is easy to correct once you know what to look for — and each is something a supervising dentist checks during the on-the-job training period.

What a Board-approved radiography course covers

Rule 64B5-9.011 prescribes the subject matter, including radiography practice and equipment, radiation biology and safety, radiographic anatomy, infection control, and hands-on instruction in positioning digital sensors and film.^[2] You can read the full rule on the Florida Administrative Code site.

FIDA's Radiography for Dental Personnel course covers those areas in five modules — foundations and radiation safety; imaging and processing; legal issues, quality assurance and infection prevention; intraoral imaging; and extraoral imaging — 14 clock hours, online and self-paced, with a clinical competency capstone completed under your supervising dentist.

Common situations

• “I take X-rays in another state.” Florida does not license dental assistants or offer reciprocity, so out-of-state experience does not convert into Florida certification.^[4] You will need Florida's on-the-job training and a Board-approved course, or a qualifying program.
• “My dentist trained me years ago.” Training alone is not certification. If you never completed a Board-approved course and the application, you are not certified.
• “I'm a new hire in my first three months.” You may position and expose radiographs as part of your on-the-job training, under direct supervision. Start a log on day one.
• “Does my certificate expire?” No. The Board states that the dental radiographer certification does not expire and does not need to be renewed.^[18]
